GnomeRR needs that too.
The backlight is exported as a normalized 0-100 value, or -1 if not
supported. Clamping to HW limits is handled by the backend.
Changing backlight uses a different method call, to avoid recomputing
the full display configuration every time the user presses the
backlight keys.
The default configuration is extended, which is only possible
if there are as many CRTCs as outputs, so make sure that's true.
Also, add more and bigger modes, so that different sizes will
be chosen for the three outputs.
A nice side effect of this is that with a real 1920x1080 + 1600x900
layout, if you disable the VGA you get a stage that matches the
screen size, which triggers the legacy fullscreen path in the
outside mutter.
Use a private output property to store if the output is in
presentation mode or not, so that this information is not lost
after the configuration read back from the server.
Ripped off libgnome-desktop, trimming the parts that checked
that the configuration was plausible, as that should be done
in gnome-control-center before asking mutter for a change.
Add a new object, MetaMonitorConfig, that takes care of converting
between the logical configurations stored in monitors.xml and
the HW resources exposed by MonitorManager.
This commit includes loading and saving of configurations, but
still missing is the actual CRTC assignments and a default
configuration when none is found in the file.
It was useful initially to evaluate the Cogl API, which might
be what we will use to wrap the low-level KMS API, but it's
incomplete and just getting in the way.
Read the current transform from XRandR, and expose the transforms
that are really supported on the bus.
The dummy backend now advertises all transforms, since it doesn't
actually apply them.
Add a number of dummy outputs and modes to the dummy backend,
and implement the writing bits.
The only visible effect is that you can change the screen size,
which resizes the output window.
Now MonitorManager does its own handling of XRandR events, which
means we no longer handle ConfigureNotify on the root window.
MetaScreen reacts to MonitorManager::monitor-changed and updates
its internal state, including the new size.
This paves the way for doing display configuration using only
the dummy backend, which would allow testing wl_output interfaces.
Implement ApplyConfiguration in terms of XRandR calls.
Error checking is done before actually committing the configuration.
If mutter is using one of the other monitor config backends, an
error is reported and nothing happens.
Turns out that even if two outputs say that they can be controlled
by a given CRTC, you can't configure them in the same CRTC unless
they are marked as "possible clones" one of the other.
This can further restrict the configuration options, so we need
to expose this limitation in the DBus API.
This new interface will be used by the control center and possibly
the settings daemon to configure the screens. It is designed to
resemble a simplified XRandR, while still exposing all the quirks
of the hardware, so that the panel can limit the user choices
appropriately.
To do so, MetaMonitorMode needs to track CRTCs, outputs and modes,
so the low level objects have been decoupled from the high-level
MetaMonitorInfo, which is used by core and API and offers a simplified
view of HW, that hides away the details of what is cloned and how.
This is still not efficient as it should be, because on every
HW change we drop all data structures and rebuild them from scratch
(which is not expensive because there aren't many of them, but
at least in the XRandR path it involves a few sync X calls)
Create a new singleton object, MetaMonitorManager, which deals
with reading the XRandR configuration and in the future applying
the new one.
This is required because xwayland will not bind the xserver interface
until he has seen the current wl_outputs, so we can't wait
until MetaScreen is built to expose them.
Consolidate all places that deal with output configuration in
MetaScreen, which gets it either from XRandR or from Cogl (which
in turn would read it from XRandR or KMS, depending on the backend).
We still need to read the Xinerama config, even when running xwayland,
because we need the indices for _NET_WM_FULLSCREEN_MONITORS, but
now we do it only when needed.
Also, now MetaWaylandCompositor listens for MetaScreen::monitor-changed
and exports the real configuration on the wayland socket.
We can't use the X11 stage window, if clutter is not using the X11
backend (and even if it was, it would be bogus when the xwayland
server is not the one clutter is talking to). Instead, we introduce
the concept of "focus type", which we use to differentiate the
various meanings of None in the focus_xwindow field.
Under X, we need to use XFixes to watch the cursor changing, while
on wayland, we're in charge of setting and painting the cursor.
MetaCursorTracker provides the abstraction layer for gnome-shell,
which can thus drop ShellXFixesCursor. In the future, it may grow
the ability to watch for pointer position too, especially if
CursorEvents are added to the next version of XInput2, and thus
it would also replace the PointerWatcher we use for gnome-shell's
magnifier.

We need to track the full xkb_state to have the necessary information
to send to the clients, otherwise they may get confused and lock
or invert the modifiers. In the evdev backend, we just retrieve the
same state object that clutter is using, while in the other backends
we fake the state using what clutter is providing (which is a subset
of what X11 provides, which would be necessary to have full state)

If mutter crashes on secondary VT, it leaves you with a raw keyboard
that doesn't switch with Alt+FN and no way to get out. At least,
let's provide a decent error message that we crash and let's
restore everything to sane defaults.
https://bugzilla.gnome.org/show_bug.cgi?id=705861
Once mutter is started from weston-launch on its own VT, there is
no way to change VT again (for example to actually start an application),
because the keyboard is put in raw mode.
So introduce some keybindings mimicking the standard X ones (Ctrl+Alt+Fn)
that switch the VT manually when activated.

When we don't have the DRM master, there is absolutely nothing
we can do (no event processing, no video output), so emulate
the old X DRM lock with a nested GMainContext without sources.
https://bugzilla.gnome.org/show_bug.cgi?id=705861
To run mutter as a display server, one needs to acquire and
release the DRM master, which is only possible for root, so
we take advantage of weston-launch, a small setuid helper binary
written for the weston project. We import our own slightly
modified copy of it, because weston-launch only launches weston,
for security reasons.

It is a very bad idea in a glib program (especially one heavily
using glib child watching facilities, like gnome-shell) to handle
SIGCHLD. While we're there, let's also use g_spawn_async, which
solves some malloc-after-fork problems and makes the code generally
cleaner.
https://bugzilla.gnome.org/show_bug.cgi?id=705816
The previous code was leaving focus fields dirty in MetaWaylandPointer
and MetaWaylandKeyboard at time (which could crash the X server
because of invalid object IDs)
The new code is more tighly integrated in the normal X11 code
for handling keyboard focus (meaning that the core idea of input
focus is also correct now), so that meta_window_unmanage() can
do the right thing. As a side benefit, clicking on wayland clients
now unfocus X11 clients.
For the mouse focus, we need to clear the surface pointer when
the metawindowactor is destroyed (even if the actual actor is
kept alive for effects), so that a repick finds a different pointer
focus.
https://bugzilla.gnome.org/show_bug.cgi?id=705859
Remove window_surfaces, as the FIXME asks for. We don't need it
because we can obtain the surface from the MetaWindow, and
follow the wayland compositor path for both types of clients.
